SPECIFICATION forming part'of Letters Patent No. 625,944, dated May 30, 1899.

Application filed March 14, 1898- To all whom it may concern.-

' Be it known that we, FREDERICK L.WHITE United States, residing at Waterbury,in the county of New Haven and State of Connecti out, haveinvented certain new and'useful Improvements in Lamp-Supports, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to devices for securing lamps to the frame of a bicycle or other vehicle; and it has for its object to provide a horizontally and atany desired angle vertically and can itself be readily secured to different parts of a bicycle-frame or to the dashboard of an ordinary vehicle.

To this end our invention consists in the lamp holding and adjusting device constructed and operating as hereinafter fully described, and particularly pointed out in the claims. i

Referring to the drawings, in which like numerals designate like parts in the several views, Figure 1 is a plan view of a lamp-holdin g device embodying our invention. Fig. 2 is a side view thereof with the clamping-bolt removed. Fig. 3 is a cross section of the clamping-arms, taken at line a: w of Fig. 1. Fig. 4 is an outer end view of the lamp-supporting post.

The numeral 1 designates a post which is rectangular in cross-section and which is preferably of hollow form, as shown in Fig. 1, from which post projects an arm 2, which terminates in a disk 3, one of the-faces of which is roughened or provided with ratchet-teeth. A similar disk 4 has a roughened or toothed face which abuts against that of disk 3 and carries means whereby it can'be secured to a lamp, such means, as herein shown, consisting of a bow-shaped arm 5, adapted to be soldered or otherwise secured to the lamp-body 6,while a bolt 7, passing centrallythrough said disks, and a thumb-nut 8, applied to said bolt, serve to lock them in any position of angular adj ustment, thus permitting the lamp to be adjusted to any desired angle vertically to the axis of the post 1. To engage and hold the having a rounded inner surface. passes through said holes in the arms and smart. 673,767. (No model.)

post 1, we have-devised a bracket composed of two arms 9 10, which are provided at one end with V-shaped jaws 12,,adapted to em brace two-opposite corners of the said post,

and-at their opposite end with V-shaped jaws '13 of a greater angle, which are adapted to closely engage either the round steering-head of a bicycle or the flattened spherical fork thereof, as shown by broken lines in Fig. 1,

. two sets of jaws the arms 9 10 are provided with holes 15 to receive the bolt 16 and with rounded bosses 17 at the outer margins of said holes, to which bosses are applied washers 18, The bolt-16 through said washers and receives upon its threaded-end the thumb-nut 19. A bowspring 20' is preferably interposed between said arms and secured thereto at its ends .by rivets, as shown in Fig. 1, which spring tends to open the two sets of jaws, while it prevents the complete separation of the arms. The arms 9 10 are preferably provided with the large central rib 21 and with the smaller ribs 22 near their opposite ends, extending longitudinally thereof to increase their rigidity, they being preferably stamped from sheet metal.

The ends of the arms 9 10 at which the jaws 12 are located are provided with the open recess 23, and the post 1 is provided with a projecting lug 24, which in the position of the parts shown by full lines in Figs.

1 and 2 enters said recess in the arm 10 and clamp-arms and holding it from. vertical movement. Such facility of adjustment enables the lamp to be carried directly in front of the part to which it is secured or to the right or left side thereof, as may be desirei, I polygonal post connected to said body by a the lamp being rigidly held in either position.

By reference to Fig. 2, it will .be observed that the holes 15 in the clamp-arms are made slightly oblong, and the slight freedom of movementthus afforded to the bolt 16, taken in connection with the rounded bosses l7 and washers 1S, prevents any cramping action between the bolt and arms and enables the jaws at the ends of the arms to adapt themselves to any slight inequalities in the surface of the parts which they engage.

The shape of the jaws 13 is such that they are not only adapted to securely engage different parts of a bicycle-frame, but also the edge of the dashboard of the ordinary fourwheeled vehicle, thus affording a wide range of usefulness to the clamping device.

' The lamp-holding means herein described is quickly and easily adjusted to secure any desired position of the lamp, is very strong and'durable, and presents a pleasing appearance when in use. Modifications in the details of construction herein shown and described can be made within the scope of our invention.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is

1. The combination with a bowshaped bracket adapted to partially embrace a lampbody and provided with a projecting disk having one of its faces toothed or roughened, of a polygonal post having an arm projecting laterally therefrom at a point substantially midway between its ends and terminating in a disk having one of its faces toothed or roughened, a bolt and thumb-nut centrally applied to said disks to hold their roughened faces in locked engagement, two clampingarms terminating at one end in V-shaped jaws which are adapted to closely engage said polygonal post, and, at their opposite end, in two V-shaped jaws of a greater angle, a clamping-bolt passing transversely through said arms between said two sets of jaws, and a thumb-nut applied to said bolt, substantially as described.

2. The combination with a polygonal post having an arm projecting laterally therefrom at a point substantially midway between its ends and having a lug projecting therefrom at substantially a right angle to said arm, of a lamp-body secured to said arm bya pivotal connection which is perpendicular to the axis of said post, two clamping-arms terminating at one end in two V-shaped jaws adapted to closely engage said post and having said ends provided with an open recess to receive the arm or lug on said post when the latter is turned about its axis, said arms terminating at their opposite end in two V-shaped jaws of a greater angle, and a clamping-bolt and thumb-nut applied to said arms between their ends, substantially as set forth.

3. The combination with a lamp-body, of a pivot-joint which is perpendicular to the axis of said post, two clamping-arms terminating at one end in two jaws adapted to closely engage said post, and, at their opposite end, in two jaws of a greater capacity and adapted to closely engage either the steering-head or fork of a bicycle, a clamping-bolt and thumb-nut applied to said arms for forcing them together, and a spring interposed between said arms and secured at its ends to the latter respectively, said spring tending to move the arms away from each other, substantially as set forth.
